Abstract

The invention provides a dual-polarized filtering antenna and communication equipment, and the antenna comprises a radiation patch; the first horizontal dielectric substrate comprises a first connecting groove, a second connecting groove, a third connecting groove and a fourth connecting groove which are arranged in the edge area of the radiation patch in a central symmetry manner; the second horizontal dielectric substrate and the first horizontal dielectric substrate are arranged at an interval; the second horizontal dielectric substrate comprises a fifth connecting groove, a sixth connecting groove, a seventh connecting groove and an eighth connecting groove which are formed corresponding to the connecting grooves in the first horizontal dielectric substrate; the capacitor loading patchis arranged on the third plate surface around the hollow area; the shape of the capacitor loading patch is the same as that of the radiation patch; and the capacitor connecting unit is electrically connected with the radiation patch and the capacitor loading patch through the corresponding connecting grooves, so that the miniaturization of the size of the horizontal plane can be realized on the premise of not performing operations such as grooving on the radiator, and high roll-off and relatively good out-of-band rejection can be realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-polarization filtering antenna and communication equipment. Background technique [0002] With the development of wireless communication technology, the requirements for communication systems are increasingly miniaturized and highly integrated, and the requirements for antenna units are also increasing. In 5G (fifth generation mobile communication technology) technology, compared with previous generations of communication systems, the energy consumption of wireless base stations has increased significantly. In order to reduce the energy loss of the base station, it is necessary to reduce the energy loss from all levels. For the dual-polarized antenna unit, it must have better polarization isolation and high roll-off characteristics. [0003] In recent years, the design of filter antennas can be simply classified into the following three categories: (1) Co-d...
